Given numbers are 561, 256, 425, 304

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 425 are 5 x 5 x 17

Prime factors of 304 are 2 x 2 x 2 x 2 x 19

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 561, 256, 425, 304

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(561, 256) = 143616

GCD(561, 256) = ( 561 x 256 ) / 143616

= 561 / 256

= 561

Step2:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

Step3:

LCM(1, 304) = 304

GCD(1, 304) = ( 1 x 304 ) / 304

= 1 / 304

= 1

So, Greatest Common Divisor of 561, 256, 425, 304 is 1
